Distributes power safely and neatly

This compact distribution block from T-Spec will handle the high-current power distribution for your multi-amp sound system, ensuring that your wiring's connected securely, looking neat, and safely fused. The set screws for the fuses have specially-designed heads that accept many common tools, even a coin, so you will always be able to change your fuse without having to carry around a special tool. Solid black nickel-plated brass construction ensures reliable power flow, and an impact-resistant plastic cover keeps the fuses and connections clean. You'll need Allen head wrenches to install this block. (Fuses sold separately.) Warranty: 1 year.

Crutchfield Customer Review (What's this?)

I been buying T-spec products for a few years now. And I have to admit that their equipment is way better than any other competitor. Power, cables, RCA cables, speaker cables etc all under the T-spec brand are the best equipment for your car audio set up.

Crutchfield Customer Review (What's this?)

The distribution block came packaged very nicely and had no troubles figuring out the install!

Pros: Allows you to fuse your system at the distribution block, I had a seperate fuse holder in my system but with this you're able to have different fuse sizes on each side specifically for each amps fuse requirements.

Cons: Was not completely descriptive that it had to have mini anl fuses

Good Product

Crutchfield Customer Review (What's this?)

The exception of losing one of the fuse mounting screws and having to find the odd metric size replacement locally this product is great. I am using it for a dual battery setup somewhat in Reverse of the planned way (I have this protecting the battery from the isolator on one side and also fused to a large aux fuse block on the other with the large cable going to the aux battery. It works perfect for my uses and the fuses come in the sizes I need to protect my equipment

Pros: price, functionality

Cons: odd metric screw size if you loose one.

Small and perfect
